(4.1) Installing IVG dependencies

The IVG dependency install file installs all the OS requirements and dependencies required for IVG. The dependency installer performs the following steps:

  • Runs prerequisite check to verify VM prerequisites are satisfied
  • Verifies if IVG is installed. If IVG is installed, it displays a list of the installed components and exits.
  • Installs OS requirements (/tmp mounting, umask settings, firewall configuration and host file configuration)
  • Installs OS dependencies.
  • Creates the ivg-installer-info.cfg which is the input file for IVG installer.

The file contains the dependency installer for:

  • RHEL\CentOS 6.10
  • RHEL\CentOS 7.7
  • RHEL\CentOS 7.8
  • RHEL\CentOS 7.9*
Note: For RHEL/CentOS 7.9
  • For RHEL/CentOS 7.9, the prerequisite installer filename is ivg-4.1-dependencies-installer-linux79. You can use this installer to update OS dependencies for RHEL/CentOS 7.9 when using IVG 4.1.
  • You must use the install_ivg.cfg configuration file generated by the IVG 4.1 Setup Wizard when running the dependencies installer for IVG 4.1 on RHEL/CentOS 7.9.

How to install IVG dependencies

Use the following instructions to install the IVG dependencies:

  • Copy the ivg-dependencies-installer file to the first VM in your IVG deployment. The installer must be in the same directory as the install_ivg.cfg configuration file created by the IVG Setup Wizard.
  • Enter the following command to change the permissions:
chmod a+x 
        ivg-dependencies-installer-
        xxxx
  • Enter the following command to execute the installer:
./
        ivg-dependencies-installer-
        xxxx
        
        install
        
  • Repeat Steps 1-3 on each VM in the IVG deployment.

After the dependencies are installed, the installer creates the ivg-installer-info.cfg which is used during IVG installation.

After you've installed the IVG dependencies, you can install IVG.
